Abstract

Abstract: Yttrium (Y 3+ )-substituted strontium hexaferrite nanoparticles with composition SrFe12- x Y x O19 have been synthesized using the sol-gel method. Diverse analytical tools have been applied to characterize the prepared strontium hexaferrite nanoparticles and to analyse the influence of yttrium (Y 3+ ) substitution on the structural and magnetic properties. X-ray diffraction patterns confirm the presence of single phase M-type hexagonal crystalline structure. In fourier-transform infrared spectroscopy, the absorption bands at low wavenumber confirmed the formation of hexagonal ferrites. The vibrating sample magnetometer has been employed to study the magnetic behavior of Y 3+ ions substituted strontium hexaferrite. The decrease in saturation magnetization (Ms ) and coercivity (Hc ) value has been explained on the basis of alteration in magnetic interactions due to the replacement of both Fe 3+ ions by the non-magnetic Y 3+ ions.
